When the RadDropDownTree contains a lot of checked items, The tooltip of the control shows all items delimited with a semicolon. For large lists it is useless (especially if the page has RadToolTip which shows a huge tooltip on screen blocking the UI). Please add an option on the control properties to disable the control from updating it's tooltip (title attribute) when items are checked

When using a RadDropDownTree with a fairly large number of items, a user may select quite a few of the items.

The current behaviour when the drop down is closed is that the names of only the first few selected items are shown, with no immediate visual feedback that more items are also selected (other than the tooltip). This can be misleading for users. 

I would like the ability to customise the message shown in the entry area, based on how many items are actually selected, e.g. "10 selected items, click here to review".
